PAYING-MACHINE.

Specification of Letters Patent.

Patented July 3, 191W.

Application filed July 31, 1912. Serial No. 712,548.

To all whom it may concern:

Be it known that I, NELSON C. OVAITT, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Paying-Machines, of which the following is a specification.

My invention relates to paying machines, and more particularly to a paying machine attachment for adding or accounting machines, or, in other words, it contemplates an inter-working combination of adding or accounting and paying mechanisms which will, by the manipulation of certain keys and levers, count or accumulate, indicate and record totals of, and pay out in coins, the amounts represented by the keys manipulated.

Among the salient objects of my invention are to provide a paying mechanism in combination with adding or accounting mechanism, capable of adding, indicating the t0- tals of, and paying out in coins, the different amounts represented by the keys or members manipulated; to provide a paying mechanism in combination with an adding or accounting mechanism capable of printing, adding and printing totals of, and paying out in coins, the different amounts represented by the keys manipulated; to provide a self-contained paying mechanism as an attachment for an adding or accounting machine, whereby it can be operated through the actuating mechanism of such adding or accounting machine; and, in general, to provide an inter-working combination of indicating, printing, adding and paying mechanisms which will, in a very simple, prac tical, accurate and economical manner, perform the various functions of the adding or accounting machine and in addition thereto, pay out coins in amounts which may be represented on the keys or members manipulated.

I am not aware thatthere has ever been produced a paying machine or a paying machine attachment for adding machines whereby it is possible to add and indicate totals of, or to record, add and print totals of, and pay out in coins, the various amounts represented upon the keys thereof manipulated, and I do not, therefore, limit my invention to the particular showing here made, which is for purposes of illustration only, but I claim the invention broadly, knowing that it is possible to embody the invention in other constructions which will be quite as effective in accomplishing the functions mentioned.

Referring now to the drawings,

Figure l is a perspective view of my invention embodied as an attachment to an adding machine, one form of adding machine now on the market having been adopted for purposes of illustrating the invention;

Fig. 2 is an end elevation, partly in sectron, showing one form of ejector mechanism, as it would appear if the paying machine were cut from the adding machine at the point indicated by the arrow, Fig. 1.

Fig. 3 is a perspective view of said ejector mechanism, showing cam and operating shafts, both of which are projected into the adding machine and operated therefrom;

Fig. 4c is a longitudinal sectional view through the cam shafts of the mechanism;

Fig. 5 shows the several groups of cam disks or rims which are mounted upon the cam shaft;

Fig. 6 is a side elevation of so much of an adding machine mechanism as will illustrate one method of connecting therewith and operating therefrom, a paying mechanism.

Referring to the drawings, my invention preferably embodied as a paying machine attachment, of such character that it can be attached to and operated through any of the well-known and practical adding machines upon the market, with very little reconstruction of the latter, and as illustrated in Fig. 1. It is possible, of course, that the invention may be embodied as a complete self-contained paying machine, having operating keys, indicating or counter wheels, recording or printing, adding and ejector, mechanisms, all so constructed and connect ed that the manipulation of the keys and levers thereof, accumulates, indicates and records totals, and ejects in coins, the amounts represented by the keys manipulated.

The paying mechanism, in the present embodiment of the invention, comprises a coin case having the usual coin racks to receive the coins of different denominations, as illustrated in Fig. 1, said racks being provided at or near their bottoms with openings through the back walls thereof for the ejector members, one form of ejector men'ibcr being illustrated in Figs. 2 and 3, which I will now describe more particularly.

27. As the slide bar 26 is moved rearwardly, the swinging arm 29 is moved proportionately so that the lower end 31 thereof is moved to a corresponding notch therein. N ow when the main shaft 1, upon which the rocker arm 32 is mounted, is turned by means of the handle 2, the rocker arm 32 is moved downwardly engaging the connecting arm 29 in its previously set position, where by the operating member or lever 30 is moved downwardly a pre-determined distance, depending upon the distance from the shaft 1 the rocker arm 32 is engaged. The operation of these members 30 operates nuineral or indicating wheels, as at 38, in the usual manner. They also operate type bats or segments, as 3 1, while the continued downward movement of the member 30 upon its fulcrum or pivot at 35, trips, at its rearward end 36, the connecting mechanism between it and a hammer 37 and permits the latter to be operated against the type segment 34, for the purpose of recording the amount manipulated upon the keys. As this particular mechanism forms no part of my invention, but is adopted for illustration purposes only from United States Patent No. 749,177, of January 12, 1904:, (granted to one D. E. Felt) 1 will not more particularly describe the indicating, printing and adding mechanism thereof, but make reference to the patent mentioned for a further description and illustration of this particular mechanism. The present embodiment of my invention is capable of attachment to and operation from any adding machine having movable parts, the movement of which is variable according to the denomination of the key pressed.

The racks 25, which operate the pinions and turn the cam shafts, are connected with such movable members, here represented as 30, whereby the downward movement thereof operates to move proportionately the rack 25, which in turn operates to rotate the pinions and cam shafts and raise the ejector arms corresponding to the keys manipulated.

Referring now to Figs. ft and 5, I will describe the manner in which the .cam shafts operate to raise the ejector levers or arms. The first row of cam disks, shown in Fig. 5, are those carried by the inner shaft 20, in Fig. 5, which said shaft and cams are turned through pinion 24:- The second row of cams, 19, are those carried by shaft 19, there be ing five of them, which shaft 19 and cams 19 are operated through pinion 23. The third row of cams .18 are those carried by the shaft 18 and are operated through pinion 22, while the last row of cams 17 are those carried by shaft 17 and are operated throiiigh pinion 21. I have indicated on the cam disks shown in Fig. 5 the denomination of each disk. lVith the combination shown it is possible to pay out any sum up to $99.99 with the machine here described. All cam disks upon each shaft are secured to and turned with the shaft, said shafts turning freely one within the other. The cam portions upon the different disks are so ar ranged and of such ertent that any eoinbination of numbers within the amount 1nen tioned can be obtained. This is accomplished in the following manner:

The cam disks in the present showing turn from right to left in the direction indicated by the arrow, Fig. 5, while in. Fig. they turn forwardly, that is, the upper portion of each cam comes forwardly and downwardly. Each disk is divided into nine equal portions, indicated by the dots, correspoialing to the nine keys in each row. The cams proper are distributed upon the peripheries; of these disks so that a cam portion will come to the uppermost position, represented. by the short vertical lines, Fig. 5, and when in this position will raise the ejector arm resting upon the cam disk, as indicated in Fig. 3. The cams are indicated on the d isles of Fig. 5 only. Thus the pressing of the 1,? key on the adding machine, referring now to Fig. 2, would rotate the cam shaft one point which would raise the ejector arm 1-; into the position indicated in dotted lines, so that when the main shaft 1 is operated, said ejector arm would be moved forward to perform its function of pushing out the coin.

Referring to Figs. 3 and -51, it will be seen that some of the ejector arms are of double thickness and work alongside a single thick ness arm within one coin stack, there being a double opening in the back wall of the coin rack, as indicated in Fig. 1. One arm will push out a single coin and the other arm will push out two coins from the same rack. The relative positions and thiclmesses of these disks and ejector arms may be seen in section in Fig. 4:.

The manipulation of any of the first row of keys of the adding machine operates through pinion 2-1 to turn m'oportionatelv to the key-manipulated shaft 20 and the four cam disks carried thereby. This operation may be briefly described as follows:

The manipulation of the onecent-key operates the inner shaft and turns the four cam disks thereupon one point, whereupon the cam of the first disk comes to the uppermost position and raises the ejector arm resting thereupon.

The manipulation of a twocentkey operates to turn the same shaft two points dis tance and brings the cams on the third disk of the row into the uppermost position, this position on the other disks being blank.

The manipulation of the tliree-centkey operates to turn the same shaft three points and brings the cams of disks 1. and 3 uppei llt most, lifting the first single ejector arm and also the double ejector arm, so as to eject two cents out of one rack and one out of the other.

The manipulation of the four-cent-key operates to turn the same shaft four points and brings cams on the second and third disks into operating position.

The manipulation of the five-cent-key operates the same shaft and brings the cam on the fourth or nickel disk into operating position.

The manipulation of the siX-cent-key opcrates the same shaft, bringing cams on the first one-cent disk and the nickel disk into operating position.

The manipulation of the seven-cent-key operates to bring arms on the third or twocent disk and the fourth or nickel disk into position.

The manipulation of the seven-cent-key operates to bring cams on the two-cent disk and on the five-cent disk into position.

The manipulation of the eight-cent-key operates to bring cams on the first, third and fourth disks into operating position.

The manipulation of the nine-cent-key operates the same shaft and brings cams. at the ninth division of all fourdisks into operat ing position.

The operation of the other rows =of keys gives the same result, paying out larger denominations. Thus if it is desired .to pay out $25.30, the 2 in the fourth row from the right-hand side of the machine, the 5 key in the third row, the 3 key in thesec- 0nd row would be pressed, these four rows from the right-hand side of the machine representing units, tens, hundreds and thousands. The corresponding cams would come into the uppermost position and the. result would be that a $20.00 gold piece, a $5.00 gold piece, a 25 piece and a nickel would be ejected by the manipulation of the ejector levers through the handle 2.

I wish to call attention to the pin and slot connection between the connecting arm 7 and the arm 10, Figs. 2 and 8. By this arrangement, the operating handle 2 can be moved sufficiently to cause the operation of the indicating, recording and adding mechanism, shown in Fig. 6, before the ejector arms are started forward, so that the indicating and recording is completed before the ejector arms move forward. The continued movement of the handle 2 then brings the ejector arms forward and ejects the coins wherever an ejector arm is raised, as will be understood by reference to Fig. 2. The ejector arms which are not raised by cams, move forward with the others, but they pass beneath the coin rack.

I am aware that the spirit of my invention can be carried out in various mechanisms wherein a working connection and coopera- ,tion between adding machines and paying machines, is .had, and I do not, therefore, limit my invention tov the form of paying machine, not the form of adding machine here shown for purposes of illustration, but claim as my invention-any machine or combination covered by the claims herein, considered in their broadest sense.

I claim as my invention:

1. In a paying machine, the combination of a plurality of coin magazines, a series of ejector arms for delivering coins from said com magazines, a bail to which said e ector amember for said bail and said .second lever whereby an operative movement of said common actuating member Wlll effect movement of the second lever to actuate the first lever and said shaft and will move the bail controlling said e ector arms.
